This application claims all rights of priority to the U.S. Provisional Patent Application Ser. No. 60/966,121, filed Aug. 24, 2007.

BACKGROUND

This application generally relates to a luggage system.

Once considered a pleasurable convenience, today's travel has shifted to become a stressful but necessary nuisance. Numerous TSA regulations and new airlines' policies have increased the inconveniences associated with travel, including luggage size and weight limits, enforced laptop removal and scanning as well as carry-on and toiletry restrictions. Therefore, the demand for smart, time-saving, and efficient travel solutions has never been greater.

Wheeled luggage cases are in widespread use today and greatly ease the traveler's movement in airports, railroad stations, etc. Many wheeled luggage items have retractable handles that permit the traveler to pull or push the luggage item as he walks and have one hand free. A common type of such a handle comprises a pair of spaced, parallel tubes that telescope into the luggage case when not needed and can be readily withdrawn into an extended position when needed.

A common practice among travelers is to carry a secondary piece of luggage, such as a laptop case, a cosmetic case or a backpack, on the wheeled luggage case by seating it on top of the case and strapping it to the extended handle. With the double tube type of handle, some stability for the secondary bag is provided by the spaced tubes. However, even with that arrangement, especially when the tubes are closely spaced, rapid movement and turning of the wheeled luggage case can cause the secondary piece of luggage to slide or twist away from its desired position on the luggage case.

An arrangement for improving the stability of a secondary bag on a wheeled luggage item, applicable to luggage cases having closely spaced double tubes or single tube retractable handles is disclosed in U.S. Pat. No. 6,938,741. That arrangement comprises a bar member mounted on the top of the luggage case and moveable between a collapsed position in which the bar member rests on the case and an extended position in which the bar member extends outwardly from the case just in front of the pull handle. The bar has considerable extent in the widthwise direction of the case, significantly more than the pull handle, and thereby provides stability to a secondary bag resting atop the case.

Another solution for attaching a secondary piece of luggage to the main wheeled luggage case includes U.S. Pat. No. 6,817,623 disclosing a case system having two equipment cases, such as for storing and transporting musical electronic equipment. The cases are connected together in an over/under relationship for the purpose of wheeling the connected cases as a single unit. The bottom case has two wheels along one edge and an extendable handle, which when extended exposes two handle shafts. The top case has two grooves which accept the two handle shafts. Latches on the top case lock the handles shafts in place within the two grooves, thereby attaching the top case to the bottom case.

With dramatic increase in the amount and frequency of business and leisure travel, there is a substantial need in the art for a luggage system enabling customization to specific lifestyle/travel needs and secure engagement and quick release of additional luggage pieces.
